Abstract
Inspired by Visibility Graph and A*, a new path planning algorithm Lambda* is presented in this paper, which needs two list as A*. But differently, Lambda* algorithm’s computation complexity is reduced by cutting down the number of vertices contained in list, this makes Lambda* algorithm find short and realistic path fast. Using Lambda* for path planning, as compared with A* algorithm, the run time decreased by 48.76% in 2D environment, 30.11% in 3D environment. Lambda* algorithm can find short and realistic looking path fast even in the complex 3D environment, and meets the demand of quickness for modern industrial robot path planning better.
